Introduction: banana water demand

Banana is a crop with high water content. 90% of the plants with a fresh weight of 200 kg at harvest are water. It takes more than 600 grams of water to assimilate 1 gram of dry matter, which shows that the water demand of bananas is very high. Under the condition of lack of water, the leaves became green and thinner, the fruit index became shorter, the pseudostem was shorter, the growth was delayed, and the harvest was delayed for more than 20 days, resulting in a reduction in yield. The high groundwater level of the banana orchard will also cause the banana root system to die of hypoxia. The annual rainfall of bananas in China is more than 1500 mm before production, but the rainfall is extremely uneven, too much rainfall in summer, and drought in autumn and winter, which is very disadvantageous to banana growth. Even in the hot summer season, banana orchards with low groundwater levels or hillsides should be irrigated if there is no rain for a week, otherwise their growth will be affected. Therefore, in order to obtain high yield, it is necessary to have good irrigation conditions. Click to get more banana planting techniques click to get more fruit planting techniques
